[151] Hereupon Flaccus received him kindly, and he lived with him. Flaccus had also with him there Aristobulus, who was indeed Agrippa's brother, but was at variance with him; yet did not their enmity to one another hinder the friendship of Flaccus to them both, but still they were honorably treated by him. However, Aristobulus did not abate of his ill-will to Agrippa, till at length he brought him into ill terms with Flaccus; the occasion of bringing on which estrangement was this: The Damascens were at difference with the Sidonians about their limits, and when Flaccus was about to hear the cause between them, they understood that Agrippa had a mighty influence upon him; so they desired that he would be of their side, and for that favor promised him a great deal of money; so he was zealous in assisting the Damascens as far as he was able. Now Aristobulus had gotten intelligence of this promise of money to him, and accused him to Flaccus of the same; and when, upon a thorough examination of the matter, it appeared plainly so to be, he rejected Agrippa out of the number of his friends. So he was reduced to the utmost necessity, and came to Ptolemais; and because he knew not where else to get a livelihood, he thought to sail to Italy; but as he was restrained from so doing by want of money, he desired Marsyas, who was his freed-man, to find some method for procuring him so much as he wanted for that purpose, by borrowing such a sum of some person or other. So Marsyas desired of Peter, who was the freed-man of Bernice, Agrippa's mother, and by the right of her testament was bequeathed to Antonia, to lend so much upon Agrippa's own bond and security; but he accused Agrippa of having defrauded him of certain sums of money, and so obliged Marsyas, when he made the bond of twenty thousand Attic drachmae, to accept of twenty-five hundred drachma as less than what he desired, which the other allowed of, because he could not help it. Upon the receipt of this money, Agrippa came to Anthedon, and took shipping, and was going to set sail; but Herennius Capito, who was the procurator of Jamhis, sent a band of soldiers to demand of him three hundred thousand drachmae of silver, which were by him owing to Caesar's treasury while he was at Rome, and so forced him to stay. He then pretended that he would do as he bid him; but when night came on, he cut his cables, and went off, and sailed to Alexandria, where he desired Alexander the alabarch to lend him two hundred thousand drachmae; but he said he would not lend it to him, but would not refuse it to Cypros, as greatly astonished at her affection to her husband, and at the other instances of her virtue; so she undertook to repay it. Accordingly, Alexander paid them five talents at Alexandria, and promised to pay them the rest of that sum at Dicearchia [Puteoli]; and this he did out of the fear he was in that Agrippa would soon spend it. So this Cypros set her husband free, and dismissed him to go on with his navigation to Italy, while she and her children departed for Judea.
